1. 1. Experiments with Visual Odometry for Hydrobatic Autonomous Underwater Vehicles

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Somnath Balaji Suresh Kumar; [2023]
   Keywords : Hydrobatic AUVs; VO; Stonefish; ORB-SLAM2; VISO2; Hydrobatiska AUV:er; VO; Stonefish; ORB-SLAM2; VISO2;

   Abstract : Hydrobatic Autonomous Underwater Vehicles (AUVs) are underactuated robots that can perform agile maneuvers in challenging underwater environments with high efficiency in speed and range. The challenge lies in localizing and navigating these AUVs particularly for performing manipulation tasks because common sensors such as GPS become very unreliable underwater due to their poor accuracy.

   Abstract : Bioinspired robots are becoming more and more common and getting inspired by the solutions found in nature to tackle problems is often useful. Regarding the swimming robots Ąeld of research, we can get inspiration from swimming snakes. READ MORE

4. 3. Development of a real-time navigation and collisionavoidance system for an autonomous naval rover : A Contribution to the Environmental Initiative for Flexible andReal-time Water Monitoring of the CatFish team

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Esmee Tackx; [2023]
   Keywords : ;

   Abstract : This thesis explores the design and optimisation of a sensor system for real-time position determination of the Fish component in the CatFish naval drone and the development of a sonar sensor system for accurate object localisation and safe navigation in dynamic and uncertain underwater conditions. Through comprehensive experimentation and analysis, this thesis demonstrates the effectiveness of the proposed sensor system and sonar sensing system in enhancing underwater navigation and obstacle avoidance capabilities.

5. 4. Design of an Autonomous underwater drone for achieving efficiency in the operation of the sensor package during monitoring of water bodies

   University essay from Blekinge Tekniska Högskola

   Author : Muaz Abdul Muti; [2022]
   Keywords : Autonomous; drone; sensor; stainless steel;

   Abstract : Background: the process of water quality monitoring is a critical quality assurance process. However, conventional methods include monitoring by a team of divers going to different depths to collect water samples. This method is expensive, time-consuming, and can lead to adverse consequences like a fatality. READ MORE

6. 5. USING N-MODULAR REDUNDANCYWITH KALMAN FILTERS FORUNDERWATER VEHICLE POSITIONESTIMATION

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Axel Enquist; [2022]
   Keywords : MATLAB; Simulink; Kalman filter; n-Modular Redundancy; Underwater;

   Abstract : Underwater navigation faces many problems with accurately estimating the absolute positionof an underwater vehicle. Neither Global Positioning system (GPS) nor Long Baseline (LBL) orShort Baseline (SBL) are possible to use for a military vehicle acting under stealth, since thesetechniques require the vehicle to be in the vicinity of a nearby ship or to surface and raise its antenna.
